Change Wan LED color depending on if the connection is up or not

I have TP link Archer c20 V4, on the stock firmware when the internet connection is not working the Wan led turns orange from green. How do i go about doing that on OpenWRT i know the stock firmware pings its website to check if the wan is receiving data or not. how can i do the same on OpenWRT.

it's device specific, you'll need to figure the exact path yourself.
in the end there should be a file called trigger, cat it, to see the available options.

Here I followed this tutorial:

GPIO

By doing so am able to change the state of the LED in software but physical pin remains Low all the time. Always the voltage of the pin is 0v.
